More rain Thursday means possible flash flooding for Denver, Front Range and Eastern Plains


As if Denver hasn’t had enough rain and flooding this week, another watch was issued by the National Weather Service for flash flooding Thursday afternoon in Denver, the Front Range foothills and most of the Eastern Plains.

The flash flood watch was issued around 2:15 p.m. and will stay in effect until late Thursday night.

Numerous slow moving thunderstorms are expected to develop this afternoon and stay into this evening, said Frank Cooper, a Boulder National Weather Service spokesman.

The storms could sit over one area for a long-time, dropping as much as 2 to 3 inches of rain in an hour, he added, which could be dangerous in some areas. If a storm becomes stationary, up to 4 inches in 2 to 3 hours is possible.

Flash flooding can cause rapid rises in rivers and streams, resulting in flooding in low lying areas. The rain could overwhelm drainage systems and flood city streets. In rural areas, roads may wash out. Mud slides are possible in mountain areas.
